Teddy, the system is going to work, no doubt about it. But the spin one usually hears on a conference call! Oy! And perhaps they are also using a tracking servo for the more gradual sway, but this doesn't help in severe vibratation situations. One of the problems I became aware of inadvertently was in the nature of the enclosures that are sometimes used on rooftops. They look like pigeon housings. Pigeons and ticker tape debris close to the transmitter or the receiver lenses will definitely obstruct traffic. No doubt about that, either. But, if a pigeon is crossing the beam path at some midpoint distance, say 200 meters from either end of a 400 meter overall link, then no... nothing will happen because there is sufficient passage on either side of the obstruction to get through. But pigeons are more likely to be problematic on rooftops and window sills where window shots take place, than they would be in a scattered midway distance. The rest of the allusions to stability were pretty funny, I thought. I wonder if they had a shot going from the Staten Island Ferry in NY City to the Statue of Liberty. Were these mentioned? If not, it's probably because they didn't think of it. Thanks for bringing up the conference call, kinda sorry I missed it. Now, how is GBLX going to use this thing? Are they are planning on getting into the network integration (VAR?) business? After the USW play... well, I've said enough here today. Regards, Frank Coluccio ps - here are a couple of throw ins which I didn't want to create a separate post for, but PMed to several folks here, already: 1.) Using Infra Red shots to get across the border. <!?!>tmex.com 2.) A FAQ sheet for more q and a, but note that some of the answers are highly subjective and favor the vendor almost exclusively. conversant.com
